When it was time to update the original site that I built for them, the Chicago Police Sergeants' Association called on me to build them a responsive site that works well on mobile devices and tablets as well as desktop computers.
Using the Wordpress platform, I was able to do this quickly and econimically. They also know have the capabilty to make small updates themselves, while I continue to be available to make larger updates.
If you are looking to update your site, let me know.
